METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is in accordance with the International System of Units (SI). The derived SIunit for force is the newton (N),
28、 which is defined as that force which when applied to a body having a mass of one kilogram givesit an acceleration of one metre per second squared (N = kgms2). The derived SI unit for pressure or stress is the newton per squaremetre (N/m2), which has been named the pascal (Pa) by the General Confere
29、nce on Weights and Measures. Since 1 ksi = 6 894 757Pa the metric equivalents are expressed as megapascal (MPa), which is the same as MN/m2 and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standard since the last issue(B62-02)-09) that may impact the
